I was at Wally World tonight and was looking at RV sewer twist lock fittings and hoses. Of course they are not 4” but then a lot of my machines don’t really need 4” and in those cases I see nothing to be gained by dragging that bigger hose around.
That RV hose is 2 1/2” and more flexible than the regular stuff and a tiny fraction of the price. There are several grades.
A quick word about part of my dust collection philosophy… I have no interest in catching every chip that is produced in my shop. I have a broom and dust pan that works quite well thank you and I find that stopping occasionally to do a quick brush-up helps keep my world in perspective and a chance to think about what I want to do next. I refuse to become frantic or rushed in a “hobby” shop. :-) I am there primarily to enjoy myself even if I am doing light production work.
I do want to get all of the fine stuff I can especially the “cloud” stuff. I don’t really care if there is a pile of heavy chips under my jointer as long as the stuff that can become air-born is sucked away. Sanding dust in particular I want to get rid of.
I know it has become sacrilegious in some guys shops to allow any chip or dust what so ever to touch a tool or the floor but that is not me.
If the tool has a 2 1/2” built in connection there is little to be gained by dragging a 4” hose over to it and connecting to a reducer. My bandsaw is like that and so is my table saw and the collectors on several of the attachments on my small herd of Shopsmiths.
Everything in my shop is on wheels except the bench and me :-) Nothing has an iron clad permanent home. I’m putting the dust collection connection points both at the walls and overhead but since the floor plan is so fluid I believe that I would like the smaller and more flexible hose in many cases. I have a 2 HP collector and a 1 1/2 HP collector. I will put them in a back room and they will have a couple of configuration options.
I’m sure that others have looked at those inexpensive twist lock fittings and thought dust collector?
